mean = add up all the numbers, then divide by how many numbers there are
for example, if we have A, B, and C, we add them up and divide by 3, since there are 3 items
mean = (A+B+C)/3

median: organize the numbers in ascending order, then find the one in the middle
if we have an even number of numbers, we take the middle two numbers and find the average
for example, if we have the numbers 1, 2, 3, 4, we take 2 and 3, which are in the middle, then take the average, which is (2+3)/2 = 2.5

mode is the number (or numbers) that appears most often. there may or may not be a mode
example 1: 1,2,2,3
2 is the mode because it appears most often
example 2: 1,1,2,2,3
1 and 2 are the modes, since they each appear most often
example 3: 1,2,3
there is no mode since all numbers appear the same number of times (once)
